  1. Update on Next-Generation Optical Initiatives in the United States Ana Preston Program Manager, International SBRC2003 Natal, Rio Do Grande Norte, Brasil 21 May 2003

  2. Internet2: Mission and Goals Develop and deploy advanced network applications and technologies for research and higher education, accelerating the creation of tomorrow’s internet. • Enable new generation of applications • Create leading edge R&E network capability • Transfer technology and experience to the global production Internet www.internet2.edu

  3. Abilene, Internet2 backbone • Towards a National Fiber Facility • Initiatives and projects • The role of Internet2 • Summary

  4. Abilene core features • U.S. higher education’s network • Natural base for community-wide efforts • Native multicast & IPv6, large MTU, measurement, advanced apps • IPv4+IPv6 common bearer services • Bandwidth availability & utilization incentive • Peering limited to U.S. & int’l R&E nets • Regional aggregation model • SONET & DWDM backhaul support • “4+ Nines” reliability target • Advanced service deployment with continuous monitoring • Open measurement platform

  5. Abilene – cont. • 10-Gbps optical upgrade nearing completion • Final backbone ’s to be installed this summer • Abilene transport (DWDM & SONET) MoU with Qwest in place through October 2006 • 2 10-Gbps connections – CENIC and Pacific Northwest • New Juniper T640 routers deployed in 2002 • 8-Gbps transcontinental test flows: IPv4+IPv6 mix & all IPv6 • Current peak load ~10% of upgraded bandwidth • Traffic doubling time ~ 1 year • Engaged national user community • 221 participants (research universities and laboratories) • Ensemble of advanced networking projects • Abilene Observatory, native IPv6, MPLS VPN test, E2E support

  6. Why a national optical facility? • Control of all network layers on national scale • Economic drivers • Expansion capability (’s) at marginal cost • Hedge • Technical drivers • New technologies: 10 Gigabit Ethernet and rational optical switching • Influencing development of new protocols at IP/optical interface • Unprecedented marketplace for both fiber and optical electronics • Contrarian opportunity for higher education • New type of network research testbed • Differentiated networks for diverse requirements • Key enabler for regional optical initiatives

  7. Optical network project scale differentiation

  8. Leading & emerging Regional Optical Initiatives • California (CENIC Optical Networking Initiative) • Connecticut (Connecticut Education Network) • Florida (Florida LambdaRail) • Indiana (I-LIGHT) • Illinois (I-WIRE) • Maryland, D.C. & northern Virginia (MAX) • Michigan • New York + New England states (NEREN) • North Carolina (NCNI) • Ohio (Third Frontier Network) • Oregon • SURA Crossroads (southeastern region) • Texas (Star of Texas)

  10. Current national optical efforts • National initiatives • National Lambda Rail (NLR) • USA Waves • Supporting projects • Fiberco • Northern Tier

  11. National Lambda Rail (NLR) • National-scale optical networking facility • 4(40)10-Gbps ’s over national footprint (16,000+ km) • Ability to provision more ’s at marginal cost • Experimental IP and switched Ethernet networks • Primary objective: support for new forms of network research • Both computer & computational science • Corporate partners • Cisco (optical transport/switching/routing) • Critical engagement of ARTI group • Level 3 (dark fiber & co-location) • Budget: $83-100M over 5 years • $50M provisionally raised for Phase 1 build

  13. NLR participation • Benefits • NLR optical node (terminals or OADM) • Access to shared experimental services (GigE & IP) • Ability to provision additional ’s across NLR at marginal cost • Responsibilities • Fundamental commitment to advancing network research • Geographic service area – optical capabilities and performance levels • $5M over 5 years to capitalize NLR build and operations

  14. NLR technology • Optical transport • Cisco 15808 LH/ELH • tributary card: 10 Gigabit Ethernet LAN PHY • Ethernet switching (GigE VPNs) • Cisco 6509 • Routing • Cisco 12410

  15. Abilene and NLR • NLR will be a fully experimental, interruptible platform • Abilene has an existing model for interconnecting with this class of network (e.g., DARPA Supernet, TeraGrid) • Interconnection and limited peering for experimentation and demonstrations

  17. Internet2 and NLR • Internet2 engaged as collaborator since December, 2001 • Working to become founding member ($10M commitment) over five years from Abilene Network reserves • Intend to offer national experimental service over a single  for first 5 years of operation – lambda grid initially • Working to complete organizational process this month

  18. Fiberco • Designed to support optical initiatives • Regional • National • Fiber options • Holding company for any future initiatives • Assignment vehicle • Regional initiatives • National initiatives (e.g., NLR) • Not an operational entity – supporting project • Will not light any fiber • Internet2 took responsibility for LLC formation • Idea was spin-off from NLR formation discussions • National Research & Education Fiber Co. incorporated • First acquisition of dark fiber for Fiberco on March 21

  19. Fiberco and Level 3 • Level 3 fiber arrangement: bifurcated contracts • Preferred provider relationship with Level 3 • 20-yr IRU • Extensible fiber arrangement • Minimum commitment of 2,600+ miles • Initial footprint flexible through September 2003 • 5-yr renewable fiber O&M and co-location/power • Fees not incurred until the fiber is lit (through May 2004) • Evaluation factors for principal fiber choice • National-scale IRU and O&M pricing available through 2006 • Aggressive open fiber interconnection policy • Homogeneous fiber type • Co-location space availability • Impact of fiber plant on total cost of system ownership (5 years) • Hut spacings, directness of fiber routing

  20. The Northern Tier project

  21. USA Waves • Internet2 was an original participant in the SURA National Buyers Consortium • First phase of cooperative agreement under active discussion between SURA and AT&T • Zero-cost lease of new dark fiber: 6,000 route-miles • Use of dark fiber for network research: 2,000 route-miles • Donation of remaining Velocita optical assets • Predominant Cisco 15800 kit • Significant opportunity for dark fiber donation • Especially in Southeast and western Northern Tier • Second phase seeks incremental pricing model for ’s with AT&T’s existing optronics • Managed service

  22. AT&T Next Generation Network

  23. Conclusions • Need for concurrent national & regional initiatives now widely recognized in U.S. • Challenges • U.S. distance scale – 16,000 km national; 2-D country • Need for regional optical networks: 3-layer hierarchy • National-scale, facility-based  network for computational science and network research • National Lambda Rail (NLR) • Supporting project for regional optical initiatives – to hold & assign dark fiber • Fiberco • Other complementary efforts in progress • USA Waves & Northern Tier
